Struct opencv::viz::WText

pub struct WText { /* private fields */ }

This 2D Widget represents text overlay.

Implementations

impl WText

pub fn new( text: &str, pos: Point, font_size: i32, color: &impl ColorTraitConst, ) -> Result<WText>

Constructs a WText.

Parameters

• text: Text content of the widget.
• pos: Position of the text.
• font_size: Font size.
• color: Color of the text.

C++ default parameters

• font_size: 20
• color: Color::white()

pub fn new_def(text: &str, pos: Point) -> Result<WText>

Constructs a WText.

Parameters

• text: Text content of the widget.
• pos: Position of the text.
• font_size: Font size.
• color: Color of the text.

Note

This alternative version of [new] function uses the following default values for its arguments:

• font_size: 20
• color: Color::white()
